6 / 9 page Application Notes (Continued) Input Stage The LM397 has a bipolar input stage. The input common mode voltage range is from 0 to (V S – 1.5V). Output Stage The LM397 has an open collector grounded-emitter NPN output transistor for the output stage. This requires an exter- nal pull-up resistor connected between the positive supply voltage and the output. The external pull-up resistor should be high enough resistance so to avoid excessive power dissipation. In addition, the pull-up resistor should be low enough resistance to enable the comparator to switch with the load circuitry connected. Because it is an open collector output stage, several comparator outputs can be connected together to create an OR’ing function output. With an open collector, the output can be used as a simple SPST switch to ground.The amount of current which the output can sink is approximately 10mA. When the maximum current limit is reached, the output transistor will saturate and the output will rise rapidly ( Figure 4). 20022107 FIGURE 4.
